Recent advances in plasmonic organic photovoltaics

Light trapping based on the localized surface-plasmon resonance (LSPR) effect of metallic nanostructures is a promising strategy to improve the device performance of organic solar cells (OSCs). We review recent advances in plasmonic-enhanced OPVs with solution-processed metallic nanoparticles (NPs). The different types of metallic NPs (sizes, shapes, and hybrids), incorporation positions, and NPs with tunable resonance wavelengths toward broadband enhancement are systematically summarized to give a guideline for the realization of highly efficient plasmonic photovoltaics.
